Introduction Erythropoietin stimulating agents (ESAs) have been established both to correct anemia and provide the clinical benefits of increased exercise capacity, reduced transfusion requirements, and improved quality of life. An increase in physician and patient adoption of biosimilars, as well as changes to healthcare reimbursement policies, have driven market competitors to innovate and expand the range of biosimilar products. While erythropoietin biosimilars have been approved by the EMA since 2007, the FDA's approval of epoetin alfa-epbx in 2018 marks the first erythropoietin biosimilar approved in the United States. Areas covered In this article, we critically review the biology, clinical use, manufacturing, safety, and efficacy of ESAs and erythropoietin biosimilars. We then review the regulatory framework and potential impact on healthcare costs offered by erythropoietin biosimilars. Expert opinion Due to the complex nature of manufacturing large-molecule biologics, it is important to recognize the challenges to quality assurance and overall safety posed by the introduction of biosimilars, which undergo much more limited clinical testing than their reference biologic product before coming to market. With many biologic therapies nearing patent expiration, biosimilars will become increasingly common in clinical practice. https://www.selleckchem.com/products/i-bet-762.html Ensuring patient safety with these products will require increased post-marketing surveillance and awareness from prescribers.Background Papillary thyroid carcinoma is the most common type of thyroid cancer; despite its generally indolent course, patients often develop local post-operative recurrences. Re-operation, however, holds a high complication rate, while at the same time, not all patients benefit from radioiodine ablation. This systematic review investigates the application of laser ablation therapy (LAT) for cervical lymph node metastases as an additional treatment modality.Methods This systematic review was conducted in accordance with the PRISMA Statement. Medline electronic database and Cochrane Library were searched for eligible articles.Results Five studies were included in the systematic review. All studies included patients with metastatic lymph nodes from papillary thyroid carcinoma, that were unsuitable for further radioiodine or surgical treatment. Patients were treated with two different LAT devices. Regardless of the utilized assessment modalities, all researchers reported significant outcomes on local disease control. No permanent complications were observed.Conclusions LAT is relatively safe and effective for the treatment of cervical metastatic lymph nodes in patients with papillary thyroid carcinoma.Introduction Flexible ureteroscopy is a commonly performed urologic procedure for visualization and treatment of the upper urinary tracts. Traditionally, ureteroscopy has been performed with reusable scopes, which have large initial purchasing costs. LithoVue was the first widely adopted single-use flexible ureteroscope clinically available in 2016 and has caused reevaluation of this paradigm. Areas covered This review is an objective assessment of the LithoVue single-use ureteroscope based on available studies at the time of publication. The authors searched major databases for papers that included the term 'LithoVue' and included relevant papers. The state of the market, technical specifications, results from clinical studies and cost analyses, and competitors are discussed. Expert opinion The LithoVue single-use flexible ureteroscope has comparable clinical performance to existing reusable ureteroscopes based on available data. Direct clinical comparisons to competing single-use ureteroscopes, many of which are relatively new, are limited. In numerous pre-clinical studies LithoVue performed favorably compared to available competitors. Cost analyses suggest that benefit of single-use ureteroscopes is institution-specific, and will likely be favorable at a low volume of cases and with high local costs for repairs of reusable scopes.Health literacy among patients is crucial for effective stroke management. The European Health Literacy Survey Questionnaire is a theory-based measure that comprehensively captures 12 domains of health literacy. We aimed to develop a computerized adaptive test of the European Health Literacy Survey Questionnaire to efficiently assess health literacy among patients with stroke.
The European Health Literacy Survey Questionnaire data of 311 patients and item parameters were retrieved from a Rasch validation study. Real data simulations were performed to develop a computerized adaptive test of the European Health Literacy Survey Questionnaire and explore its efficiency and reliability.
The computerized adaptive test of the European Health Literacy Survey Questionnaire displayed suitable reliability in all 12 domains (0.72-0.84) with a mean test length of 17 items (36.2% of the 47-item European Health Literacy Survey Questionnaire).
Our findings indicate that the computerized adaptive test of the European ractice. Developing of the computerized adaptive test of the European Health Literacy Survey Questionnaire provided findings that may benefit researchers and clinicians interested in developing efficient outcome measures.The fibroblast growth factor receptor (FGFR) pathway is essential in cell proliferation, differentiation, migration, and survival. Cancers such as intrahepatic cholangiocarcinoma (IHCA) have demonstrated alterations of FGFR allowing unregulated growth. Infigratinib (BGJ398) is a potent ATP-competitive inhibitor of all four FGFR receptors as demonstrated by the consistently high prevalence of hyperphosphatemia, indicating disruption of FGFR-related phosphate homeostasis.
In this article, the authors discuss preclinical studies and the biological characterization of BGJ398 that inspired its investigation for cancer treatment. They summarize results from phase I and II studies and comment on ongoing phase III clinical trials primarily focusing on its role in treating IHCA.
Infigratinib exhibitshigh potency FGFR1-3 inhibition in preclinical studies. Clinically, agents targeting FGFR including infigratinib show promising anti-tumor activity in targeted trials. Pemigatinib, an FGFR inhibitor, has recently been approved by the FDA for use in refractory IHCA.
